I'm not actually sure what my lead qualifies as. I suspect anti-lead but I only started competitive battling 4 days ago.
It's a Gallade that has managed to take down almost every single lead pokemon it has come across in one hit. Exceptions being scizor, fortress and ferrothorn.
Course this is on pokemon online as the one I have in the games while bred the way I want it to be is only level 56 right now. Similarly for the other 2 that I transferred. Bred properly but not the proper levels.
More on topic, I have a reunicleus that I am going to try using as a special tank/attacker and am working on getting a chandelure for special offense.... I just realized I have maybe 2 for physical offense.... hrmm...
